RH calibration humidity (Salt) References - EE-HA010401

The EE humidity calibration set is a convenient way to expose sensors to RH of 5, 10, 35, 50, 80 & 95% for checking or calibration. Solutions come in sets of 5 glass ampoules. The air above the salt solutions will hold a fixed RH at a certain temperature which is not STRONGLY temperature dependent. High accuracy calibration can be attained if the temperature is held very constant, and the variation from the reference temperature is allowed for error correction. The sensor is isolated from the liquid by a semi permeable membrane.

Versions for horizontal use

Convenient & simple

Accuracy ±0.5% at 23 ±2°C for 10% RH and up to +/-1.2% at high RH - see data sheet
